Thanks, but how does this address the PR?  This is the full text of 
PR 12918:

  There is no (obvious) documented way to get a symtab_and_line object given an
  arbitrary address.  
  A function gdb.sal_for_pc() similar to gdb.block_for_pc() would be nice.

If you want to tell that decode_line is the answer for the PR's
request, then why not update the documentation of decode_line, which
is almost 2000 lines earlier in the manual and in a different node?

IOW, why are you adding this text in this particular place?

Sorry if I'm missing something obvious.
