whenever the next direction in the path string is bad. It then passed
the whole path string to shp_path(), which makes no sense unless we're
at the beginning of it, but luckily failed in that case. Change to
try path finding right after prompting for new input.
true.
(shp_nav_one_sector): Pass false. This lets minesweepers move at the
speed their stats indicate. Closes#1498801.
(navi): Pass true. This ensures sweeping without moving still costs
mobility.
obeys conditionals. Use snxtsct_dist(). Closes#785447. Only march
and test were actually broken, the other uses zapped conditionals.
(move_map, fly_map, nav_map, navi): Don't zap conditionals.
silly EF_NMAP. Use characters instead: 'b' for bmap (was EF_BMAP),
't' for true bmap (was EF_MAP), 'r' for revert (was EF_MAP+EF_BMAP,
more sillness), and 'n' for nmap (was EF_NMAP). Callers changed.
(EF_NMAP): Remove.
effect. Replace calls by struct assignment where possible. Replace
clear buffer, copy string to buffer by strncpy(). Use assignment to
clear when that's clearer. Replace overlapping copy through bounce
buffer by memmove(). Replace rest by standard memset() and memcpy().
Also use sizeof() instead of literal array sizes for robustness, and
instead of symbolic array sizes for clarity.
