- dedent_lines(+In, -Out, +Options)
- Remove shared indentation for all lines in a string. Lines are separated
by "\n" -- conversion to and from external forms (such as "\r\n") are
typically done by the I/O predicates.
A final "\n" is preserved.
Options:
- tab(N)
- Assume tabs at columns of with N. When omitted, tabs are
taken literally and only exact matches are removed.
- chars(CodesOrString)
- Characters to remove. This can notably be used to remove
additional characters such as
* or `|`. Default is
" \t".
