Details:

When PHP code contains heredoc ending markers that are indented (available
since PHP 7.3), it seems that it is not detected. Result is that strings
located in following code source are not extracted.

See in joined file (test.php).
- The heredoc block that starts on line 6 should end on line 8, but its ending
marker is indented and not detected.
- String on line 11 is ignored, as considered in a heredoc block.
- The heredoc ending marker on line 16 is taken for ending marker of previous
heredoc block, as it has the same name.
- The heredoc block that starts on line 22 should end on line 24, but its
ending marker is indented and not detected.
- String on line 27 is ignored, as considered in a heredoc block.
- The heredoc ending marker on line 32 has no effect, as it has a different
name than previous heredoc block.

Attached test.po file was generated using following command line: 
xgettext test.php -L PHP --force-po --keyword=_:1 -o test.po
