Re-saving with the Patch Manager causes "P" hooks to continually get longer

[Spleeeeen]

• Open a ROM
• Open the Patch Manager
• Press the "Add" button
• Press Browse and select a C patch file* which includes the "P" signifier in the Hook
• Press OK, then Save
• Open the Patch Manager again. The Hook is now (correctly) 4 bytes longer. If you press Edit, you can see that it comes after the "P".
• Save the Patch Manager, then Open it again. Notice that the Hook is 4 bytes longer.
• Repeat the previous step any number of times; the Hook will continue to grow.

*Here is an example of a file which will generate the problem: https://hatebin.com/cbbiomfryi

Reproduced. The hook string shown in the manager is actually not supposed to display the address from the P identifier.
