Though, one has to be careful about the fact that str* functions often
stop on NULs and that strbufs may have embedded NULs.

Functions
---------
* Related to the contents of the buffer
+`strbuf_trim`::
+
+ Strip whitespace from the beginning and end of a string.
+ Equivalent to performing `strbuf_rtrim()` followed by `strbuf_ltrim()`.
+
`strbuf_rtrim`::
Strip whitespace from the end of a string.
+`strbuf_ltrim`::
+
+ Strip whitespace from the beginning of a string.
+
+`strbuf_reencode`::
+
+ Replace the contents of the strbuf with a reencoded form. Returns -1
+ on error, 0 on success.
+
+`strbuf_tolower`::
+
+ Lowercase each character in the buffer using `tolower`.
+
`strbuf_cmp`::
Compare two buffers. Returns an integer less than, equal to, or greater
Remove the bytes between `pos..pos+len` and replace it with the given
data.
+`strbuf_add_commented_lines`::
+
+ Add a NUL-terminated string to the buffer. Each line will be prepended
+ by a comment character and a blank.
+
`strbuf_add`::
Add data of given length to the buffer.
`strbuf_addbuf`::
- Copy the contents of an other buffer at the end of the current one.
+ Copy the contents of another buffer at the end of the current one.
`strbuf_adddup`::
destination. This is useful for literal data to be fed to either
strbuf_expand or to the *printf family of functions.
+`strbuf_humanise_bytes`::
+
+ Append the given byte size as a human-readable string (i.e. 12.23 KiB,
+ 3.50 MiB).
+
`strbuf_addf`::
Add a formatted string to the buffer.
+`strbuf_commented_addf`::
+
+ Add a formatted string prepended by a comment character and a
+ blank to the buffer.
+
`strbuf_fread`::
Read a given size of data from a FILE* pointer to the buffer.
Strip whitespace from a buffer. The second parameter controls if
comments are considered contents to be removed or not.
+`strbuf_split_buf`::
+`strbuf_split_str`::
+`strbuf_split_max`::
+`strbuf_split`::
+
+ Split a string or strbuf into a list of strbufs at a specified
+ terminator character. The returned substrings include the
+ terminator characters. Some of these functions take a `max`
+ parameter, which, if positive, limits the output to that
+ number of substrings.
+
+`strbuf_list_free`::
+
+ Free a list of strbufs (for example, the return values of the
+ `strbuf_split()` functions).
+
`launch_editor`::
Launch the user preferred editor to edit a file and fill the buffer
