/*
 * The concept of the "file" routines below (and elsewhere) is that all
 * file handling should be done using as few routines as possible, since
 * every machine is slightly different, but these routines always have the
 * same semantics.
 *
 * In fact, perhaps we should use the "path_parse()" routine below to convert
 * from "canonical" filenames (optional leading tilde's, internal wildcards,
 * slash as the path seperator, etc) to "system" filenames (no special symbols,
 * system-specific path seperator, etc).  This would allow the program itself
 * to assume that all filenames are "Unix" filenames, and explicitly "extract"
 * such filenames if needed (by "path_parse()", or perhaps "path_canon()").
 *
 * Note that "path_temp" should probably return a "canonical" filename.
 *
 * Note that "my_fopen()" and "my_open()" and "my_make()" and "my_kill()"
 * and "my_move()" and "my_copy()" should all take "canonical" filenames.
 *
 * Note that "canonical" filenames use a leading "slash" to indicate an absolute
 * path, and a leading "tilde" to indicate a special directory, and default to a
 * relative path, but MSDOS uses a leading "drivename plus colon" to indicate the
 * use of a "special drive", and then the rest of the path is parsed "normally",
 * and MACINTOSH uses a leading colon to indicate a relative path, and an embedded
 * colon to indicate a "drive plus absolute path", and finally defaults to a file
 * in the current working directory, which may or may not be defined.
 *
 * We should probably parse a leading "~~/" as referring to "ANGBAND_DIR". (?)

 * before this function returns.  Thus they function just like normal
 * parameters, except that most calls to this function can ignore them.
 *
 * If "inkey_xtra" is TRUE, then all pending keypresses will be flushed,
 * and any macro processing in progress will be aborted.  This flag is
 * set by the "flush()" function, which does not actually flush anything
 * itself, but rather, triggers delayed input flushing via "inkey_xtra".
 *
 * If "inkey_scan" is TRUE, then we will immediately return "zero" if no
 * keypress is available, instead of waiting for a keypress.
 *
 * If "inkey_base" is TRUE, then all macro processing will be bypassed.
 * If "inkey_base" and "inkey_scan" are both TRUE, then this function will
 * not return immediately, but will wait for a keypress for as long as the
 * normal macro matching code would, allowing the direct entry of macro
 * triggers.  The "inkey_base" flag is extremely dangerous!
 *
 * If "inkey_flag" is TRUE, then we will assume that we are waiting for a
 * normal command, and we will only show the cursor if "hilite_player" is
 * TRUE (or if the player is in a store), instead of always showing the
 * cursor.  The various "main-xxx.c" files should avoid saving the game
 * in response to a "menu item" request unless "inkey_flag" is TRUE, to
 * prevent savefile corruption.
 *
 * If we are waiting for a keypress, and no keypress is ready, then we will
 * refresh (once) the window which was active when this function was called.
 *
 * Note that "back-quote" is automatically converted into "escape" for
 * convenience on machines with no "escape" key.  This is done after the
 * macro matching, so the user can still make a macro for "backquote".
 *
 * Note the special handling of "ascii 30" (ctrl-caret, aka ctrl-shift-six)
 * and "ascii 31" (ctrl-underscore, aka ctrl-shift-minus), which are used to
 * provide support for simple keyboard "macros".  These keys are so strange
 * that their loss as normal keys will probably be noticed by nobody.  The
 * "ascii 30" key is used to indicate the "end" of a macro action, which
 * allows recursive macros to be avoided.  The "ascii 31" key is used by
 * some of the "main-xxx.c" files to introduce macro trigger sequences.
 *
 * Hack -- we use "ascii 29" (ctrl-right-bracket) as a special "magic" key,
 * which can be used to give a variety of "sub-commands" which can be used
 * any time.  These sub-commands could include commands to take a picture of
 * the current screen, to start/stop recording a macro action, etc.
 *
 * If "angband_term[0]" is not active, we will make it active during this
 * function, so that the various "main-xxx.c" files can assume that input
 * is only requested (via "Term_inkey()") when "angband_term[0]" is active.
 *
 * Mega-Hack -- This function is used as the entry point for clearing the
