Thank you! This looks great. The attached revision makes a a couple of minor
changes:
* Change the line wrap of the docs to be more like the rest of func.sgml
* Remove an unnecessary nested if statement
* Removed `==` from one of the test comments
* Ran pgindent to create the attached patch
A few other brief comments, entirely stylistic:
* I kind of expected pg_base64url_encode to appear immediate after
pg_base64_encode. In other words, to see the two uses of
pg_base64_encode_internal adjacent to each other. I think that’s more typical
of the project standard. Same for the functions that call
pg_base64_decode_internal.
* There are a few places where variable definition has been changed without
changing the meaning, for example:
- const char *srcend = src + len,
- *s = src;
+ const char *srcend = src + len;
+ const char *s = src;
Even if this is desirable, it might make sense to defer pure formatting
changes to a separate patch.
* You define return variables in functions like pg_base64url_enc_len rather
than just returning the outcome of an expression. The latter is what I see in
pg_base64_enc_len, so I think would be more consistent. Io other words:

I suspect these are the sorts of things a committer would tweak/adjust before
committing, just thinking about getting ahead of that. I think it’s ready.
