Hi ! I was doing some translations on Weblate and I ran into this string :

https://github.com/jnavila/git-manpages-l10n/blob/master/en/git-send-email.txt#L228

Furthermore, passwords need not be specified in configuration files or on the command line. If a username has been specified (with `--smtp-user` or a `sendemail.smtpUser`), but no password has been specified (with `--smtp-pass` or `sendemail.smtpPass`), then a password is obtained using 'git-credential'. 

--smtp-user, sendemail.smtpUser, --smtp-pass, and sendemail.smtpPass are enclosed in backticks, but git-credential is enclosed in apostrophes.

I assume it's a typo and therefore the translation should use backticks ?

I didn't do a PR proposing a fix because I'm not very familiar with po files and from what I understand modifying the original string would break the translations ? (I'm not a developper sorry if I misunderstand how they work ^_^")
