Subject: bug#4177: 23.1; whitespace-mode and typing spaces
Date: Mon, 17 Aug 2009 11:05:49 -0400 [thread overview]
Message-ID: <19081.29133.813431.847848@winooski.ccs.neu.edu> (raw)
`whitespace-mode' is generally very useful, but there are some
annoyances:
* Unlike `show-trailing-whitespace', spaces at the end of a line are
shown even if the cursor is right after them. This means that just
typing some text is flashing the highlights on and off (I'm sure
that this would be extremely unpleasant if I wouldn't have chosen a
very quiet color for that...).
* In a similar way, if you type some stuff on a first line, then hit
enter a few times, the whole empty part is highlighted (if empty
line at the bob/eob are highlighted). This is similar because in
this case it is also likely that more text will eventually be
entered.
* There is another problems with highlighting the initial/final
segment of empty lines -- looks like it's the problem of using
font-lock with a multi-line pattern, which means that it's not
dealing with it gracefully (eg, adding a line will un-highlight only
the line right next to it). Together with the last point, this
means that if you do something like this (in a fresh buffer):
foo RET RET RET RET bar RET
you're left with the middle highlighted.
