Thank you for the pull request!
I am not sure here as the docs say in vhost configurations the leading slash is always included:
https://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriterule

It sounds weird to me that Debian should patch their apache package to break with upstream behavior?
Maybe it is your RewriteBase?

Hi @susnux ,
I was not familiar with the official docs, but am I misreading the 5th bullet point under 'per-directory' settings? This looks like you would never need a forward slash at the start of your rewrite rules?

The removed prefix always ends with a slash, meaning the matching occurs against a string which never has a leading slash. Therefore, a Pattern with ^/ never matches in per-directory context.

Anyway, I'm not an expert, so if you believe this PR is not correct, don't feel bad about rejecting it :).

Only if in .htaccess or <Directory> context.

That is correct, but I also read:

Although rewrite rules are syntactically permitted in <Location> and <Files> sections (including their regular expression counterparts), this should never be necessary and is unsupported. A likely feature to break in these contexts is relative substitutions.

I did indeed place the Rewrite-block in a directory section, which explains why it is working for me, but at the same time renders it clear that the PR is not entirely correct
