fix Subversion prompt (#7278)

Browse source 
* fix Subversion prompt

- after switching to "string match", some SVN status symbols need
  proper escaping
- the __fish_svn_prompt_flag_names list was missing
  "versioned_obstructed" and was therefore not in line with
  the symbols from __fish_svn_prompt_chars
- when checking for individual SVN status symbols, use
  "string match -e" to handle the case where multiple different
  symbols appear in one status column
- use "sort -u" before merging all symbols from a column into
  one line

Fixes #6715

* use regex for SVN status matching

Using regex matching will prevent different match behaviour
depending on qmark-noglob feature.
Also, counting the resulting matches is unnecessary.

* use list instead of string for SVN status

Make $column_status a list be not removing newlines from SVN status
output. This makes checking for the individual status types within
a column easier because it doesn't require regex matching.

* added quotes for string length test (-n)
