tldr: Default search path

[DUO-1337]

my os is Manjaro Linux x86_64
[ymcold@ymcold-vmwarevirtualplatform ~]$ strace.py tldr tar ... getpeername(3, 0x00007ffeb4090220, 0x00007ffeb409021c) = 0 getpid() = 1936 (0x0000000000000790) getpid() = 1936 (0x0000000000000790) getpid() = 1936 (0x0000000000000790) getpid() = 1936 (0x0000000000000790) getpid() = 1936 (0x0000000000000790) getpid() = 1936 (0x0000000000000790) write(3, 0x0000562fb2ff0db0, 517) = 517 (0x0000000000000205) read(3, 0x0000562fb2fe7b93, 5) = -104 ECONNRESET (Connection reset by peer) ioctl(3, 21537, 140731918909500) = 0 close(3) = 0 openat(-100, '/home/ymcold/.cache/tldr/pages/linux/tar.md', O_RDONLY|O_CLOEXEC (0o2000000), O_RDONLY) = -2 ENOENT (No such file or directory) Error fetching from tldr: <urlopen error [Errno 104] Connection reset by peer> write(2, 'Error fetching from tldr: <urlopen error [Errno 104] Connection reset by peer>\n', 79) = 79 (0x000000000000004f) ioctl(1, 21505, 140731918918048) = -25 ENOTTY (Inappropriate ioctl for device) rt_sigaction(SIGINT, 0x00007ffeb4092a50, 0x00007ffeb4092af0, 0x0000000000000008) = 0 sigaltstack(NULL, 0x00007ffeb4092d00) = 0 sigaltstack(0x00007f16e023ad20, NULL) = 0 exit_group(1) *** Process 1936 exited with code 1 ***
when i use tldr tar, it only search the ~/.cache/tldr/page/linux/, but tar.md ~/.cache/tldr/page/common;I think the the default search path should be /page/os and /page/commen ;

Sorry for missing this issue. We already do first search for the OS specific page before falling back to common. However, as indicated in #118, we make network requests for each searched location. Instead, as stated there, we should check if we have any matching files on the filesystem first and use them before making network calls.

Closing this as I think it's just a duplicate.
