Man page using :samp: with braces - font doesn't reset

[ghost]

There are issues with the man page rendering when using :samp:{blah}
The font change doesn't reset after the closure of the samp but runs onto subsequent lines until certain 'resetting' elements are encountered, such as a bullet, heading and probably others I haven't tested for.
:samp:like this is ok. HTML and Latex (pdf) formats are also unaffected by this issue.

MWE included with screen shot.

Manpage Test

:samp:Sample Text (with 'samp') {and this text in braces}

Text that should be plain.

• A bullet that should be plain.

And back to normal.

:samp:{this text in braces} but not this

More text that should be plain.

• A bullet that should be plain.

And back to normal.

:samp:Now a 'samp' with no braces

All ok on this line.

Apparently, I face the same problem with the latest release 4.0.2:

index.rst:

Welcome to demo documentation!
==============================

This is :samp:`fine`.

Show :samp:`{problematic}` underscore starting here.

And this is also bad.

conf.py:

project = 'Demo project'
copyright = '2001-2021 XYZ'
authors = 'Me'

man_pages = [
    ('index', 'demo', 'GNU project C

and template Makefile is needed:

$ make man
man _build/man/demo.1
$ grep problematic _build/man/demo.1
Show \fB\fIproblematic\fP\fP underscore starting here.

Apparently, it's problematic only when a :samp: directive begins with {. I've got a patch for it.
