While attachments are probably okay for a one-shot contribution, if your
intent is to become an active contributor for Outreachy, you'll
definitely want to fix your outgoing mail setup to work with inline
patches sent directly from 'git send-email' rather than forcing everyone
else to deal with your unusual workflow.

Is there a patch 1/3 and 2/3 (and if so, where's the cover letter 0/3)?
Or did you mean for this to be a single-patch series, at version 3?
Given that the content has gone by before, I suspect the latter; to
achieve that, use 'git send-email -v3'.
You're also missing a category, and patches should generally favor
imperative tense (think "[apply this patch to] do this") rather than
past tense ("[this patch] did this"). Also, you want the subject line
to be a short how; the commit body can be used for further explanations.
So a better commit message might be:
util: Switch malloc to g_malloc in envlist.c
Also switch matching free to g_free.
Done as one of the suggested bite sized tasks

g_malloc() can't fail (rather, it fails by exit()ing), so any code
checking for NULL is now dead code, and should be cleaned up as part of
the same conversion patch.

Is the cast still necessary? Are we casting away const? It's useful to
mention why a cast is present, if it is necessary; otherwise omit it as
part of cleaning up the code.

g_new() is better than g_malloc() if you are going to multiply two
values, to make sure you don't overflow the multiplication.
