Edit to add:

Prevent wrapping
This fixes a cosmetic issue with Internet Explorer where a wikilink followed immediately by an in-text cite may cause the link and cite to be underlined together; not supported by IE6 and IE7

This will join the in-text cite to the preceding text, preventing it from wrapping; it does not add a space; does not work for Internet Explorer

Add a space before the in-text citation
This will join the in-text cite to the preceding text, preventing it from wrapping; a space will show between the text and the in-text cite; not supported by IE6 and IE7

Inconspicuous in-text citations
The :before and :after pseudo-elements are not supported by IE6 and IE7

Pop-ups
To add pop-ups for the in-text citation that show the full citation, see User:Blue-Haired Lawyer/Footnote popups.

Also, the Gadget at Special:Preferences->Browsing->Reference Tooltips.
