If we're doing nicer markup+CSS for this, then it might make sense to
find a better solution for this kind of entry with multiple signatures
(which was already an issue in the previous version):
text || anynonarray or anynonarray || text → text
Converts the non-string input to text, then concatenates the two
strings. (The non-string input cannot be of an array type, because that
would create ambiguity with the array || operators. If you want to
concatenate an array's text equivalent, cast it to text explicitly.)
'Value: ' || 42 → Value: 42
I think it would make sense to split the first line to put each of the
two signatures on their own line. So it would look like this:
text || anynonarray
anynonarray || text → text
Converts the non-string input to text, then concatenates the two
strings. (The non-string input cannot be of an array type, because that
would create ambiguity with the array || operators. If you want to
concatenate an array's text equivalent, cast it to text explicitly.)
'Value: ' || 42 → Value: 42
Another example:
to_ascii ( string text [, encoding name or integer ] ) → text
should be (I think):
to_ascii ( string text [, encoding name ] ) → text
to_ascii ( string text [, integer ] ) → text
