when in wdired buffer , or wgrep-mode buffer , some text is read only , I think iedit should skip these read-only text.
so I open ths pull request .
you can see
the variable query-replace-skip-read-only in replace.el
or function wdired-isearch-filter-read-only in wdired.el
skip read-only text
maybe if in an readonly buffer , you can ignore this option (like query-replace-skip-read-only)
if you don't think this is a good idea ,you can plus a toggle option ,
I am not familiar with iedit , so can you implement it.
or maybe you can set read-only text in different face , and skip read only text when apply changes on them
Merge branch 'master' of git://github.com/victorhge/iedit
Read-only text is set in a different face and skipped now.
