The following dynamic replacement strings are also activated. They are
inspired by bash's parameter expansion:
{:-str} str if the value is empty
{:num} remove the first num characters
{:pos:len} substring from position pos length len
{#regexp} remove prefix regexp (non-greedy)
{##regexp} remove prefix regexp (greedy)
{%regexp} remove postfix regexp (non-greedy)
{%%regexp} remove postfix regexp (greedy)
{/regexp/str} replace regexp with str
{^str} uppercase str if found at the start
{^^str} uppercase str
{,str} lowercase str if found at the start
{,,str} lowercase str
{:-str} str if the value is empty
{:num} remove the first num characters
{:pos:len} substring from position pos length len
{#regexp} remove prefix regexp (non-greedy)
{##regexp} remove prefix regexp (greedy)
{%regexp} remove postfix regexp (non-greedy)
{%%regexp} remove postfix regexp (greedy)
{/regexp/str} replace one regexp with str
{//regexp/str} replace every regexp with str
{^str} uppercase str if found at the start
{^^str} uppercase str
{,str} lowercase str if found at the start
{,,str} lowercase str
