[parted-devel] [PATCH] Make ---pretend-input-tty inhibit output word-wrap.

[Jim Meyering]

Another tiny patch, for improved testability.
Without this patch, testing expected output against actual was
a royal pain, since I have to edit the expected output file to
match the wrapping performed by parted itself, and that depends
on "screen width".  With this change, using the ---pretend-input-tty
option disables the bothersome wrapping:

	Make ---pretend-input-tty inhibit output word-wrap.
	* parted/ui.c (screen_width): Use effectively-unlimited screen width
	with ---pretend-input-tty, just as for '--script' mode.

This probably breaks the existing tests, but, as I said, they're
about to be replaced wholesale with better ones.
