            Bug ID: 78745
           Summary: Truncated messages in po file
           Product: gcc
           Version: 6.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: translation
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fmarchal at perso dot be
  Target Milestone: ---

Multiline parameter descriptions in gcc/c-family/c.opt are truncated in po
files provided to translators.

For instance, on line 1053:

fcheck-pointer-bounds
C ObjC C++ ObjC++ LTO Report Var(flag_check_pointer_bounds)
Add Pointer Bounds Checker instrumentation.  fchkp-* flags are used to
control instrumentation.  Currently available for C, C++ and ObjC.

is seen by the translator as

#: c-family/c.opt:1055
msgid "Add Pointer Bounds Checker instrumentation.  fchkp-* flags are used to"

That message can't be translated as only the first line is visible.
