s/-S <regex>/-S<block of text>/ and
s/the specified string/the specified block of text/ would make it
more in line with how Documentation/gitdiffcore.txt explains it.
The original discussion from early 2017 also explains with a pointer
why the primary mode of -S is not <regex> but is <block of text>.

Same comment as the one for 1/2 applies here.

Other than these, I think both patches look sensible.  Thanks for
resurrecting the old topic and reigniting it.
