Subject: [PATCH] Fix ibuffer-mark-by-file-name-regexp abbreviations

* lisp/ibuf-ext.el (ibuffer-mark-by-file-name-regexp): Prefer
read-regexp over read-string for reading regexps.  Determine file
name using ibuffer-buffer-file-name for consistency.  Abbreviate
file name using ibuffer-directory-abbrev-alist (bug#18859).
