I've heard that the perl script mg (stands for "multiline grep") has
similar option -c0, for example:

$ cat test.txt
aaatestaaatestbbb
abatestbaa

$ mg -c0 -E '[abc]+' test.txt
aaa
aaa
bbb
aba
baa

(Mg is available from ftp://ftp.iij.ad.jp/pub/IIJ/dist/utashiro/perl/)

I'm not well aware of uses of --context, but --context=0 is still
useful?  In current implementation of context control, it seems hard to
change the semantics of the context control options -C, -A, -B, because
the commonly used function context_length_arg only accepts a positive
integer.
