[PATCH] TUI, Source files with CRLF line endings

[Ton van Overbeek]

When dealing with source files containing DOS CR/LF line-endings
on Cygwin I found that these did not get correctly displayed in
TUI's source window. Every line from the top of the window is
followed by an extra empty line.
This can happen on Cygwin if you open a DOS file with CR/LF line-endings
on a binary mounted file system.
The fix is to add some logic to tuiSetSourceContent to swallow the extra
LF characters[B.
Changelog entry and patch attached.

	* tuiSource.c (tuiSetSourceContent): Eat the extra '\n' in
	source files containing '\r\n' line endings.
