Added information about how llvm-as and llvm-dis select the input and output
filenames.
Corrected some typos in the llvm-dis documentation.

SYNOPSIS

-llvm-dis [options] < filename>
+llvm-dis [options] [filename]
<h3>
DESCRIPTION
</h3>
The llvm-dis command is the LLVM disassembler. It takes an LLVM bytecode file
-and converts it into one of several human readable formats.
+and converts it into LLVM assembly language or C source code with equivalent
+functionality.
+<p>
-By default, llvm-dis places its output in filename.ll, removing the .bc suffix
-if it exists.
+If filename is omitted, llvm-dis reads its input from standard input.
+<p>
+
+The default output file for llvm-dis is determined by the following logic:
+<ul>
+ <li>
+ If the input is standard input or the file -, then the output is standard
+ output.
+ <p>
+
+ <li>
+ If the input filename ends in .bc, then the output filename will be
+ identical, except that the .bc suffix will be replaced by the .ll or .c
+ suffix (for LLVM assembly language and C code, respectively).
+ <p>
+
+ <li>
+ If the input filename does not end in .bc, then the output filename will be
+ identical to the input filename, except that the .ll or .c suffix will be
+ appended to the filename (for LLVM assembly language and C code,
+ respectively).
+</ul>
