When an invalid if structure is placed on the same line as an event declaration, the "invalid format" error message will omit the file/line information vital to debugging. This only happens when the if statement is placed on the same line as the declaration.

Steps to reproduce:

1. Place the following code in a remote script:
Code:
on *:TEXT:*:?:if x x

2. Type //msg $me hi

This will display: "* /if: invalid format" without line information.

3. Change this to:
Code:
on *:TEXT:*:?: {
  if x x
}

4. Repeat //msg $me hi

This will properly display the file and line number:

* /if: invalid format (line 30, script.mrc)

Also happens with raw events and I assume this is the same for ctcp.
