Grep Searching node in building.texi

[Juri Linkov]

I checked the node `Grep Searching' and want to propose the following
corrections.  I think mentioning the `-nH' option is essential
(and also I find the phrase `where there were' too clumsy).

  @findex grep
    Just as you can run a compiler from Emacs and then visit the lines
! where there were compilation errors, you can also run @code{grep} and
  then visit the lines on which matches were found.  This works by
  treating the matches reported by @code{grep} as if they were ``errors.''
  
    To do this, type @kbd{M-x grep}, then enter a command line that
  specifies how to run @code{grep}.  Use the same arguments you would give
! @code{grep} when running it normally: a @code{grep}-style regexp
  (usually in single-quotes to quote the shell's special characters)
  followed by file names, which may use wildcards.  If you specify a
  prefix argument for @kbd{M-x grep}, it figures out the tag
