Markup which infinite-loops the doc server

[dtonhofer]

The markup

| =|*|= | only for non-leaf types: subtypes exist which are =|?|= and others which are =|!|=.  |

is deadly to the doc server:

The page is not displayed, and the CPU really gets a good workout.

Trying to stop SWIPL results in a segmentation fault or

?- ^D
% halt
% The following threads wouldn't die: ['httpd@4000_1']

I feel there is a runaway regex in there.

I feel there is a runaway regex in there.

Except there are no regexes 😄

My feeling betrayed me! But that's my Perl heart...
