Fix incomplete string escaping or encoding

[kreeksec]

fix the problem, replace text.sub('\\', '') with text.gsub('\\', '') so that all occurrences of the backslash character are removed from the string, not just the first one. This change should be made only on line 297 in the handle_regexp_SUPPRESSED_CROSSREF method in lib/rdoc/markup/to_rdoc.rb. No additional imports or method definitions are required, as gsub is a standard Ruby String method. This change preserves the intended functionality while ensuring that all backslashes are removed, not just the first.

Could you also share an input that reproduces this problem and the actual result and expected result with the input?

It seems that RailsActiveRecord::Base::sanitize_sql https://api.rubyonrails.org/classes/ActiveRecord/Sanitization/ClassMethods.html#method-i-sanitize_sql doesn't use backslack.

@markup.add_regexp_handling(/\\\S/, :SUPPRESSED_CROSSREF)

A string that matches /\\\S/ (two length string starts with ) is passed to handle_regexp_SUPPRESSED_CROSSREF.

Example rdoc format:

== See \RDoc and \Array and \Hash. Use backslash(\\)

Example target passed to handle_regexp_SUPPRESSED_CROSSREF: "\\R", "\\A", "\\H", "\\\\"

Expected output:

== See RDoc and Array and Hash. Use backslash(\)

target is always two-length string that starts with \ and only the first backslash should be removed. If second char is \, it should remain.
text.sub is enough. text.gsub will wrongly removes escaped backslashes.
