.htaccess broken regex for \.orig and \.save

This bug didn't exist in 7.34, but does in 7.38. Not sure where along the way it was introduced.

<FilesMatch "\.(engine|inc|info|install|make|module|profile|test|po|sh|.*sql|theme|tpl(\.php)?|xtmpl(~|\.sw[op]|\.bak|\.orig|\.save)?$|^(\..*|Entries.*|Repository|Root|Tag|Template)$|^#.*#$|\.php(~|\.sw[op]|\.bak|\.orig\.save)$

This line in .htaccess used to have \.bak|\.orig|\.save)$ at the end, but now has \.bak|\.orig\.save)$. Note the missing '|'. the '|' exists in the other regular expression in the string, so I assume this isn't on purpose.
