Details:

Comments are described in section 2.2 of the Revised7 Report on the
Algorithmic Language Scheme (R7RS,
https://small.r7rs.org/attachment/r7rs.pdf).

With xgettext 0.19.8.1, line comments and block comments seem to be handled
well, but not datum comments.

Example Scheme file, test.scm:

(string-append
  ;(i18n "Laboratory")
  #;(i18n
      "Instrument")
  #|
   (i18n "Analyst")
   |#
  (i18n "Method"))


When I run
> xgettext --language=Scheme --keyword=id:i18n test.scm
the output PO file erroneously contains the "Instrument" msgid.
