[PATCH] man2/bpf.2: srcfix: Some fixes that only change fonts

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



1) Use single-font macros for a single argument.

2) Use quotation marks for arguments containing a space.

3) Use roman font for punctuation marks.

  The output has only changes of the font for a punctuation mark.
