CSS rules for wiki controls can conflict with wiki content

[anonymous]

How to reproduce:

1. Edit any wiki page

2. Add two headings to the page, one called 'save', the other 'Save'

   = save
   = Save
   

3. Preview the page

4. Notice how the 'save' heading is indented, while 'Save' is not.

wiki.css has the rule

#delete, #rename, #save { margin-left: 3em }

to indent the 'Submit Changes' input element among others, but headings are given the ID of their content, so there's a conflict here with the 'save' heading, and a number of other possible heading titles.

This could be fixed by adding a element selector to the wiki CSS rules

input#save

or using a new class for wiki controls and divs and adding it to the CSS rules, or renaming the ID of the controls, or any number of other ways.
