:
: If I understand SUSv3 correctly, file names or label names can contain
: semicolons:
:
: 32406 Command verbs other than {, a, b, c, i, r, t, w, :, and # can be
: followed by a semicolon, optional
: 32407 <blank>s, and another command verb. However, when the s command verb
: is used with the w
: 32408 flag, following it with another command in this manner produces
: undefined results.
:
: GNU sed, which by default accepts semicolons after (at least) the : and t
: commands does not strictly conform. I'd rather that our sed was by default
: as close as possible to what the standard requires, so we probably do need
: a command line option like you suggested.
:
: I think -g would be a better choice (similar to m4's -g option) to
: emphasise the fact that accepting semicolons after these commands is a GNU
: extension, and possibly adding more GNU compatibility features if
: they're needed/useful. BSD, 7th Edition and System V all behave the same
: way, and treat semicolons as part of the label/filename.
