I tend to agree that if we do not give a way to toggle between
"with" and "without" color when piping to a program, it is safer to
make the default uncolored.
Good point. The default behavior or "|xyz" should be to strip
the coloring escape sequences, because we don't know is "xyz"
capable of handling those escape sequences properly, and to keep
the coloring with "||xyz" or whatever we come up with for our
equivalent "--color=always", so to speak.
The user's configured pager is expected to deal with colors just
fine (or the user has globally configured colors to be off). As we
are capable of telling if the user is asking to spawn the default
pager (by not giving a custom command or by clearing the previous
custom command given in the same session) or a custom one, it should
be easily doable to give colored version to the configured pager and
uncolored version to a custom/one-shot command. Unlike the existing
support for (e)dit command, we do not read back from what the
command does using the hunk and present it again to the user, it
should be a relatively easy and safe thing to do.
Exactly.
