This commit broke bootstrapping - well, at least kind of:
make pdf (and probably 'make dvi' and other formats using TeX)
now fails with:
Runaway argument?
-Wanalyzer-tainted-allocation-size @gol -Wanalyzer-tainted-array-inde@ETC.
src/gcc-mainline/gcc/doc/invoke.texi:96
82: File ended while scanning use of @doignoretext.
The problem seems to be that when producing TeX output, the '...' of
@gccoptlist{ ... }
ends up in a single line. Thus, '@ignore' is found but no
corresponding '<newline>@end ignore'.
Using '@c' has the same problem. And adding a line break will give
an error as @gccoptlist does not permit another paragraph in
the argument.
My solution is move the '@ignore' comment after the closing '}'.

doc/invoke.texi: Move @ignore block out of @gccoptlist [PR103533]
With TeX output ("make pdf"), @gccoptlist's content end up in a single
line such that TeX does not find the matching '@end ignore' for the
'@ignore' block – failing with a runaway error. Solution is to move
the @ignore block after the closing '}'.

support enabled.
