Description:
if (1)
{
append_file $MYSQLTEST_VARDIR/tmp/master0.expect;
wait
EOF
echo one;
}

echo ok;

Running the above test (with --record) goes ok.
Changing "if" to "while" one gets:
mysqltest: At line 7: End of file encountered before 'EOF' delimiter was found

Debugging shows that it's the second iteration of the loop which fails to parse: the read_until_delimiter() starts its search from the blank line before "echo ok", no wonder it does not meet the EOF delimiter.
The example above has an infinite loop but comes from a real-life problem.

How to repeat:

      Bug #32296 mysqltest fails to parse "append_file" inside a "while", it works inside a "if"
      Bug #41913 mysqltest cannot source files from if inside while
      Some commands require additional processing which only works first time
      Keep content for write_file or append_file with the st_command struct
[29 Jul 2009 13:41] Bjørn Munch 
The extra field in struct st_command is only used by append_file or write_file, and only *needed* by those if in a while loop, so it might seem a bit overkill. It seems the easiest way to manage it though.

You should probably also add a test to mysqltest.test
