nirvana replacements.tsv file.txt -o file.txt

Where a replacements.tsv file looks like this:

ADDRESS	RE	REPLACEMENT	FLAGS
,	foo	bar	2

The program will escape whitespace and other relevant characters in both the RE and REPLACEMENT columns, so no special regex commands like ,s/foo/&&/g etc.

Of course, it relies on /bin/ed, so not fully portable.
