WoMan generates different result from man?

[Hongxu Chen <leftcopy.chx@gmail.com>]

Hi all,

  I am using `WoMan' other than man to read manpages. But I find there
  are some slight differences when reading the content.  Take the
  manpage of `man' as an example:

  WoMan parses the result of the section number introduction like this:

     1@Executable programs or shell commands 
     2@System calls (functions provided by the kernel) 
     3@Library calls (functions within program libraries) 
     4@Special files (usually found in /dev) 
     5@File formats and conventions eg /etc/passwd 
     6@Games 
     7@Miscellaneous (including macro packages and conventions), e.g. man(7),
      groff(7) 
     8@System administration commands (usually only for root) 
     9@Kernel routines [Non standard] 

  While the result generates by `man' does have `@' but spaces `   ',
  just as follows:
  
       1   Executable programs or shell commands
       2   System calls (functions provided by the kernel)
       3   Library calls (functions within program libraries)
       4   Special files (usually found in /dev)
       5   File formats and conventions eg /etc/passwd
       6   Games
       7   Miscellaneous (including macro packages  and  conventions),  e.g.  man(7),
           groff(7)
       8   System administration commands (usually only for root)
       9   Kernel routines [Non standard]

  The margin in WoMan also seems a little odd.

  So is this a known issue?

  Thanks!
