Only outputs if -p >= 2

[Synray]

Same issue as #14
In the radare2 source tree, from folder radare2/libr/core, coccigrep will only output results if I set -p 2 or higher. It seems to only work reliably with -p 3 or higher.
This outputs nothing:

coccigrep -t 'RDisasmState' -a 'show_reloff' *c

While this works:

coccigrep -t 'RDisasmState' -a 'show_reloff' *c -p 3

output:

disasm.c:654 (RDisasmState *ds):                ds->show_reloff = r_config_get_i (core->config, "asm.reloff");
disasm.c:2289 (RDisasmState *ds):                       if (ds->show_reloff) {

Likewise this this doesn't work:

coccigrep -t 'RDisasmState' -a 'show_reloff' *c -p 1

[regit]

I'm using the latest git from coccigrep and I got result with coccigrep -t 'RDisasmState' -a 'show_reloff' *c -p 1

Coccinelle version is 1.0.4.deb-3+b4
