[1/3] grep: perform some minor code and comment cleanups

Commit Message

Dragan Simic March 20, 2024, 9:08 p.m. UTC

Move some variable definitions around, and reflow one comment block, to
make the code a bit neater after spotting those slightly unpolished areas.
There are no functional changes to the source code.

Notes:
    This patch is salvaged from my earlier series, [1] for which it has been
    concluded to be not acceptable for merging, because of possible issues
    with various git scripts. [2]
    
    Compared to the previous version, there are no changes in this version.
    As expected and as already discussed, patches like this one inevitably
    raise a few eyebrows. [3][4][5]
