This patch is bogus. Both versions are completely correct.
The purpose of escaping in this context is to prevent mdoc(7)
from treating the exclamation mark as a delimiter, which can
influence spacing and end of sentence detection.
The mdoc(7) language treats the argument of an mdoc macro
as a delimiter if both of the following conditions hold:
1. The macro argument consists of exactly one input character.
2. That character is anyone from the following set:
- opening delimiters: ([
- middle delimiters: |
- closing delimiters: .,:;)]?!
The usual way to escape an argument such that it isn't taken as
a delimiter is to add a zero-width space "\&" such that condition 1
no longer holds. See the mdoc(7) manual, subsection "Delimiters",
for a full discussion.
I admit that i usually put the "\&" in front of the character rather
than after it, and so do the examples in the mdoc(7) manual. But
some people find it more intuitive to put the "\&" afterwards to
express that the character is not ending a sentence (i.e. is not a
delimiter).
I don't see the point in enforcing either style, it seems like
useless churn and wasted time.
Yours,
Ingo
