Comment 2 for bug 742041

In natty, if the type characters match a singe directory entry, pressing the TAB key results in the matching entry, with:
1: A space following
2: No escaping of embedded spaces or special characters

This is NOT related to unity - it appears for the classic desktop as well

In previous releases, bash would do the following:
1: For embedded spaces, they would be escaped with a single backslash ("\")
2: If the match was a directory, the displayed match would terminate with "/' (eg "Desktop/") and NO trailing space
3: A trailing space would be appended ONLY in the case where there was a single file name that matched when the TAB was pressed

bash version:
