Subject: [PATCH v3 5/6] doc:git-for-each-ref: fix styling and typos

From: "Jean-Noël Avila via GitGitGadget" <[email-masked]>
Date: Mon, 11 Aug 2025 20:53:19 +0000

From: =?UTF-8?q?Jean-No=C3=ABl=20Avila?= <[email-masked]>

This commit fixes the synopsis syntax and changes the wording of a few
descriptions to be more consistent with the rest of the documentation.

It is a prepartion for the next commit that checks that synopsis style is
applied consistently across a manual page.

+Iterate over all refs that match _<pattern>_ and show them
+according to the given _<format>_, after sorting them according
+to the given set of _<key>_.  If _<count>_ is given, stop after
+showing that many refs.  The interpolated values in _<format>_
 can optionally be quoted as string literals in the specified
 host language allowing their direct evaluation in that language.
