The change of color context is done per line (except in normal.c where at the moment it is per hunk but I will change it to be per line) so the most it can hang is the time needed to print a single line. > Also, 'diff --color' needn't mess with signal handling unless isatty > (fileno (outfile)). Should this also be done if --color=always is used? Thanks, Giuseppe
