Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug. If you can, give a recipe
starting from `emacs -Q':
Write the following in a .js file:
{
-2,
2,
+2
}
Then, put your cursor over each line and press tab to indent it.
The lines having -2 and +2 get twice as much indentation as expected.
The line having just 2 has the correct indentation.
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/usr/share/emacs/24.3/etc/DEBUG.
