[PATCH] cmd.exe: increase size of WCMD_HandleTildeModifiers() buffers to MAXSTRING

[Damjan Jovanovic]

Some buffers in WCMD_HandleTildeModifiers() are only of size MAX_PATH,
even though
they handle strings that aren't necessarily filenames. When changed to have size
MAXSTRING, a stack overflow crash with strings of size MAX_PATH stops happening.
