           Summary: Broken handling of manpages containing ".BI ... \"
                    lines
           Product: kio
           Version: 4.4
          Platform: Debian testing
        OS/Version: unspecified
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: man
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: ewoerner at kde.org


Version:            (using KDE 4.4.0)
Installed from:    Debian testing/unstable Packages

This bug has been copied over from
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=557364 and has been verified
to still exist in KDE SC 4.4.0

The pages from manpages-dev package (sections 2 & 3) have lines starting with 
.BI in Synopsis section, used to pretty-format function declarations. 

Sometimes these lines are terminated with a backslash, for example in the man 
pages for msgsnd, wait, mmap, ipc, setbuf, dbopen, etc. There are 46 files in 
section 2, and 169 in section 3 with lines matching the pattern "^.BI.*\\$" 

When displaying one of these man pages with KDE Man Page Viewer the function 
declaration is corrupted. For example, instead of:

        int msgsnd(int msqid, const void *msgp, size_t msgsz, int msgflg);

        ssize_t msgrcv(int msqid, void *msgp, size_t msgsz, long msgtyp,
                      int msgflg);

there is:

    int msgsnd(int msqid, const void *msgp, size_t msgszmsgflg);

    ssize_t msgrcv(int msqid, void *msgp, size_t msgszmsgtyp,
               int msgflg);

More precisely, looking at the man page source one could see that the quoted 
string after the \ on the previous line is lost.
