bug#55742: 29.0.50; Confusing "pcase" documentation on the web

[Rudolf Adamkovič]

In "The pcase macro" documentation on the web

https://www.gnu.org/software/emacs/manual/html_node/elisp/pcase-Macro.html

has "_" on its own line, surrounded with whitespace.  It looks like a
dash, and in a graphical browser, one has to select it to discover the
mistake.  Could we add the word "underscore" somewhere next to it?
