   - implement blank `Bl -column', such as
     .Bl -column
     .It foo Ta bar
     .El
   
 - FIXED OpenBSD term.h 1.16 term.c 1.30 mdoc_term.c 1.75 schwarze 23.4.10  - explicitly disallow nested `Bl -column', which would clobber internal
   handle tab characters outside literal context, e.g. usb(4)    flags defined for struct mdoc_macro

   NEEDS MERGING TO bsd.lv  
   
 - FIXED OpenBSD man.h 1.15 libman.h 1.16 man_hash.c 1.9  - set a meaningful default if no `Bl' list type is assigned

   man_term.c 1.28 man_html.c 1.9 schwarze 25.4.  
   implement .if .ie .el

   - have a blank `It' head for `Bl -tag' not puke
   
   - ignore horrendous m[] font colouring
     reported by J.C. Roberts
   
   - prohibit `Nm' from having non-text HEAD children
     (e.g., NetBSD mDNSShared/dns-sd.1)
     (mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified)

 - URGENT, this is making many kernel manuals look bad:  
   .Ft/.Fn should MAYBE behave in custom section like in SYNOPSIS?  
   autoconf.9:  
     .Sh DIRECT CONFIGURATION  
     .nr nS 1  
     .Ft "struct device *"  
     .Fn config_found_sm "struct device *parent"  
   groff:

       config_found_sm(struct device *parent, ...

 - indentation got lost in SYNOPSIS, e.g.

         date [-ajnu] [-d dst] [-r seconds] [-t minutes_west] [+format]  
   -          [[[[[[cc]yy]mm]dd]HH]MM[.SS]]
