@{{{  @regexp Origami Regular Expressions
Origami supports regular expression search and replace. The syntax widely
conforms POSIX extended or basic regular expressions.

@{{{  Replace Expressions
In regular expression replace, the following special expressions are allowed
(any character, not used for special purpose, can be used for itself):

@ref-start-tbl Expression 10 Meaning(*) 52
\<x> @@ the <x>-th group in the search pattern
\u<x> @@ the <x>-th group, all characters uppercase
\l<x> @@ the <x>-th group, all characters lowercase

\!<x><e>} @@ <s>, if the <x>-th group does not match
\} @@ }
\\ @@ \
@ref-end-tbl
@ref-start-item (*)
<x> can be 0 .. 9 and g10 .. g16. The <x>-th group is the part of the
matching string, matched by the part of the regular expressions in the
<x>-th pair of (). 0 is used for the complete string. <e> is a replace
expression and <s> the corresponding string.
@ref-end-item
@ref-start-item (**)
For short strings <s>, the last character will be used for padding. Use
`\0' as last character to prevent padding.
