I think that it's not expected and I see it a bug.
glob2regpat() gives what look like unexpected
results for:
:echo glob2regpat('a\=')
Actual: ^a\=$
Expected: ^a\\=$
:echo glob2regpat('a\+')
Actual: ^a\+$
Expected: ^a\\+$
:echo glob2regpat('a\d')
Actual: ^a\d$
Expected: ^a\\d$
And many probably many other cases
where \ is special in regexp, but not special
in glob special characters.
I believe this is not true. The documentation mentions this:
,----[ :h file-pattern ]-
| *file-pattern*
| The pattern is interpreted like mostly used in file names:
| * matches any sequence of characters; Unusual: includes path
| [...]
| \ special meaning like in a |pattern|
| [...]
`----
So one can expect '\=' to work like a regexp pattern.
Best,
