[PATCH] git-gui: Remove space from the end of aspell's reply before processing

[Johannes Sixt <j.sixt@viscovery.net>]

From: Johannes Sixt <johannes.sixt@telecom.at>

When git gui processes a reply from aspell it explicitly ignores an empty
line. The Windows version of aspell, however, terminates lines with CRLF,
but TCL's 'gets' does not remove CR, hence, a "visibly" empty line was not
actually recognized as empty. With this change we explicitly trim off
whitespace before the line is further processed.

Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at>

 There's probably a better solution by having TCL do the translation of
 line endings, but I don't know how to do that.
