The manSubHeading is defined as syn match manSubHeading "^\s\{3\}[a-z][a-z ]*[a-z]$"
This will, however, match more lines than I think is intended. It will, for example, match the line \t returns are what are recorded and compared with the data git keeps where "\t" is a horizontal tabulation. I'm guessing that the actual regex should be ^ \{3\}[a-z][a-z ]*[a-z]$ but I'm not sure; I haven't been able to find a reference for the display of manual pages. Anyone have any insight into this issue? nikolai
