Summary0000792: Make "reader" in "open_read_file" return a line number beside the string.
DescriptionThe "reader" function returned by "open_read_file" currently has the following syntax:

  function (<table> env)
    return <string> line
  end

It would be nice if it were:

  function (<table> env)
    return <string> line, <number> lineno
  end

where "lineno" would be the line number assigned to that line, no matter what it is in the original file. If missing, that number would be the previous line number + 1.


Rationale:
I often transform \input files on the fly from e.g.

  one
  two
  three

to

  one
  \environment
  two
  \endenvironment
  three

If line numbers could be assigned as:

  1. one
  2. \environment
  2. two
  3. \endenvironment
  3. three

that'd make error reporting behave as if on the original file, and SyncTeX could also getting things right.

adding it to the callback is complex and asks for problems (as we don't want to make a number returned mandate)

the following is more flexible anyway:

tex.getlinenumber() -- reports the current number
tex.setlinenumber(n) -- just sets it
tex.setlinenumber(n,true) -- adds n to the current number
