Please plan ahead for an environment variable getting too large, or the
environment getting too full, or the number of arguments getting too

I'd favour possibly large data going into a temporary file with the
filename in an environment variable.

    mail -s "$NUM_PATCHES applied to $REPO" droundy <$PATCH_SUMMARIES

How do other SCMs handle this?
